AI Technical Summary

Benefits of technology

The graphene-enhanced balloons provide a high strength-to-thickness ratio, enabling access to difficult-to-reach areas and withstanding higher pressures, thus improving the efficacy of medical procedures like angioplasty while maintaining a low profile.

Problems solved by technology

Examples of problems that may be encountered with conventional balloons relate to the balloon thickness and strength.
Due to the profile of such a balloon, there is limited access to certain areas of the body.
Moreover, conventional materials may only allow for minimal inflation pressures and may burst if subjected to certain elevated pressures when such pressures are necessary to dilate, for example, a narrowed artery.

Abstract

Inflatable medical balloons are disclosed herein. The inflatable medical balloons include balloon walls that are reinforced with graphene. The balloon walls can include any number of layers and one or more of the layers may include graphene. Catheters including the medical balloons are also disclosed in addition to methods for manufacturing the inflatable medical balloons.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims the benefit of U.S. Provisional Patent Application No. 62 / 008,979, filed Jun. 6, 2014, the contents of which are incorporated into the present application in their entirety.BACKGROUND[0002]1. Field of the Invention[0003]The present disclosure generally relates to medical devices. More particularly, the disclosure relates to reinforced medical balloons.[0004]2. Description of the Related Art[0005]Balloon catheters are widely used in the medical profession for various intraluminal procedures. One common procedure involving the use of a balloon catheter relates to angioplasty dilation of coronary or other arteries suffering from stenosis (i.e., a narrowing of the arterial lumen that restricts blood flow).[0006]Although balloon catheters are used in many other procedures as well, coronary angioplasty using a balloon catheter has drawn particular attention from the medical community because of the growing number ...
